Mamas&Papas Cybex Aton CarSeat Gatecrashing from due in July

Just want to know if any of you fairly new Mum are using the Cybex Aton car seat from Mamas and Papas, and if so your thoughts??

I know it does not come with an isofix/surefix base option and only has seat belt install...

I have been set on getting a seat which has a fix base, but would like to know if any one has experience of this car seat first and truly how much of a drag is it to use the seat belt? Am also posting this in a few other places so appologies if anyone sees more than once.

I don't have this seat but I can advise on having to use the seat belt v's isofix as I have the Maxi Cosi Cabriofix and started off just using the seatbelt in my car but it was driving me crazy as we have the family fix base in my OH's car which is the best thing ever! I ended up buying another base for my car!

It's not a big deal to use the seatbelt if you have a 4/5 door car but the isofix bases are so much more convienient and quick which is great when your shopping and trying to get shopping, buggy and car seat in the car!

I haven't used the seat either, have the britax SHR one, but have had a base in my ccar since the start and its been great...so much easier its amazing, especially if its peeing down with rain, after 3 months use I can practically throw the car seat into the car and jump in and we're away!

I know it is a little more ?????? to buy a base but its money well spent, especially when you think you'll prob use it everyday for atleast 4 months! On the other hand it depends what type of car you have, we have a golf so its quite small to get seat into, however my SIL had 3 babies in a Landrover discovery, because of the height and size differences she felt she never needed a base with hers and got pretty niifty with the belt!
